Hi everybody, i have a problem with my application.

I have a mac m1 and i have installed sonoma at 14.0, and i have my iphone 12 at 17.0.3. On my mac i have an xcode version at 15.0.1 ( 15A507 ) with installed the iOS 17.0.1.

I have released my app on testflight and on my device it's correctly working, while on an Iphone 13 pro max with iOS 16.6.0 the app it's crashing. I tried to install on my mac the sdk for ios 16.4, clean and rebuild the app on a iphone 14 with ios 16.4 and release the app on testflight. On my pc the app with the simulator it's correctly working, on my iphone with iOS 17 it's working, on the iphone with 16.6.0 it's not.

Whenever i build i click on 'Any iOS simulator Device ( arm64, x86_64 ) and the build target is iOS 12

If you need anything else feel free to ask.

Thank you in advance!

Upgrade any outdated dependencies in your project. Some dependencies may have conflicts with the latest Xcode version that do not cause a crash in iOS 17, but do cause a crash in older iOS versions. And you won't find any obvious hints to this in your logs. It is difficult to know what dependency is causing the issue without knowing how your app is built. I ran into this with the Flutter connectivity_plus dependency.
